Adalbert, Duke of Lorraine

He was the first son of Gerhard IV, Count of Metz, and Gisela (Gisella), possibly a daughter of Theodoric I, Duke of Upper Lorraine.

Gerard's father Adalbert had inherited the county of Metz from his brother Gerhard of the Moselle.

Irritated, Godfrey rebelled in that same year and devastated his suzerain's lands in Lower Lorraine.

Godfrey continued to fight for all Lorraine and Adalbert died in battle against him at Thuin on 11 November 1048.

He had no known sons,[1] and Henry III, Holy Roman Emperor immediately nominated his brother Gerhard to succeed him.
